What it does

Use it to help a fantasy league commissioner run a fair, fun league in any sport, covering league setup, scoring and roster settings, schedule and playoff format, waiver and trade rules, trade vetoes and collusion checks, rule disputes and rulings, inactive managers, dues handling, and keeping the league healthy year to year.

  • Should I veto this trade?
  • What settings should we use?
  • Someone's tanking, what do I do.

  • Two guys are fighting over a rule.

How it works

A skill is a set of expert instructions Claude loads whenever you ask about your team. It pins down your league's exact rules first, checks current news when it can, then makes the call.

Install in a minute

  1. Download the ZIP from the link in your email. Don't unzip it: Claude wants the ZIP as it is.
  2. Open Skills in Claude. On claude.ai or the desktop app, open Customize, then Skills. On some versions it's under Settings, Capabilities, Skills.
  3. Upload it. Click +, choose Create skill, then Upload a skill, and pick the ZIP. One ZIP per upload.
  4. Check it's on. The skill should show as enabled. Skills work on any Claude plan, including the free one. Just turn on code execution in Settings, Capabilities.
  5. Start a new chat and ask about your team, for example "Help me set my lineup this week." Claude loads the skill on its own when it's relevant.
